We should not use /dev/sda and /dev/sdb in our examples. Users might
inadvertently mess up their workstation. Use /dev/sdX instead.
Remove console output like '# ' and '> ' which makes copying hard.
Set example language to bash for correct syntax-highlighting.

With sifive_fu540_defconfig:
User can use FSBL or u-boot-spl.bin anyone at a time.
For FSBL,
fsbl->fw_payload.bin (opensbi + U-Boot)
For u-boot-spl.bin,
u-boot-spl.bin->FIT image (opensbi + U-Boot proper + dtb)
U-Boot SPL will be loaded by ZSBL from SD card (replace fsbl.bin with
u-boot-spl.bin) and runs in L2 LIM in machine mode and then load FIT
image u-boot.itb from SD card into RAM.
U-Boot SPL expects u-boot.itb FIT image at the starting of SD card sector
number (0x822) of GUID type "2E54B353-1271-4842-806F-E436D6AF6985"

Add compressed Image parsing support so that booti can parse both
flat and compressed Image to boot Linux. Currently, it is difficult
to calculate a safe address for every board where the compressed
image can be decompressed. It is also not possible to figure out the
size of the compressed file as well. Thus, user need to set two
additional environment variables kernel_comp_addr_r and filesize to
make this work.
Following compression methods are supported for now.
lzma, lzo, bzip2, gzip.
lz4 support is not added as ARM64 kernel generates a lz4 compressed
image with legacy header which U-Boot doesn't know how to parse and
decompress.
Tested on HiFive Unleashed and Qemu for RISC-V.
Tested on Qemu for ARM64.

We should explicitly load DTB from TFTP server or MMC/SD card
for Linux booting. This will allow us:
1. To use different Linux DTB for SiFive Unleashed board with
expansion board connected.
2. Avoid re-flashing OpenSBI firmware whenever board connections
change.
This patch updates reference bootlog in SiFive FU540 README
as-per above.
